VISE

Specification of Letters Patent. Application led. June 26, 1908. Serial No. 440,517.

No. 993,659. Patented June 1, 1909.

pivot, away from the jaw 5, to release the same by means of a bell crank lever 10. pivotally mounted upon the bracket 7 and provided with an operating rod 11 pivotally connected to and extending from one end thereof, and provided with an angular outer end projecting beneath the shank 4, forwardly of the frame 1, the other end of said bell crank lever 10 being adjacent the friction member 6 to forcibly bear against the same when said operating rod 11 is pulled. From the direction of movement of the friction member 6 to release the sliding shank 4, it will be apparent that inits clamping movement toward the frame 1, the slidingly adjustable jaw 5 need only have the weight of the operators body thrown thereagainst in order to move the same. When however, it is desired to move said jaw 5 in the opposite direction, the operating rod 11 must first be pulled to release the friction member 6.

The stationary fr ame 1 carries a clamping jaw 12 opposing the slidingly adjustable jaw 5, which jaw 12 comprises an inverted U-shaped frame having the ends of its extensions pivotally mounted upon the frame 1 adjacent the lower portion thereof, and straddling the jaw shank 4, and provided with an upper cross piece in alinement with the jaw 5. Leaf springs 13, secured to the lower port-ion of the frame 1, and bearing against the extensions of the pivoted jaw 12, normally maintain said jaw in close relation with the frame 1, while means are provided for forcibly locking said jaw 12 upon To all who/m it may concern- 4 Be it known that I, CHARLES It. KELLY, citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Vises, of which the following` is a specification.

My invention relates to vises embodying opposing jaws between which work may be clamped, and of that character which are adjustable in order that the same may be adapted to work of different sizes.

The object of my invention is to provide a vise which may be more readily and quickly adjusted to clamp the desired work, and which in its clamping adjustment, will not necessitate the use of the operators hands.

In the accompanying drawings, in which my invention is shown, Figure 1 is a side elevation of a vise constructed in accordance with my invention with its treadle connection broken away. Fig. 2 is an end elevation thereof. Fig. 3 is a vertical longitudinal sectional view taken therethrough. Fig. 4 is a side elevation of a slightly modi fied form of the body of my improved vise and the clamping jaw carried thereby and Fig. 5 is a side view of the treadle connection for my improved device.

In the practical embodiment of my invention, I provide a stationary body comprising a rectangular frame 1, mounted upon a bed plate 2, adapted to be attached to a suitable support by bolts 3. Mounted to slide through the frame 1, is an elongated shank 4, of the slidingly adjustable jaw 5, which shank 4 is provided with a relatively deep slot extending longitudinally thereof, from its lower face and adapted for the reception of a suitable locking mechanism whereby the said jaw 5 may be locked in the desired adjustment with respect to the body portion 1. Said locking mechanism comprises a round nosed friction member 6, pivotally mounted at its lower end upon a stationary bracket 7 extending within the slot of the jaw shank 4 which round nose is adapted for engagement against the interior surface of the shank 4 under the action of a coil spring 8, of the desired strength in order to more tightly clamp the work held between-said jaws after the jaw 5 lhas been moved into engagement with the same.

The above mentioned means for swinging the pivoted jaw 12 comprise a rotatable shaft 14, journaled through the upper portion of the frame 1, and provided upon its outwardly extending ends, with disks 15 secured eccentrically thereon, the peripheries of which disks bear against the swinging jaw 12, and when rotated, operate to force said jaw 12 toward the jaw 5. In order to rotate the shaft 14 and the disks 15 carried thereby, I provide arms 16 centrally journaled upon the eXtreme ends of the shaft 14, and provided with openings at each side of its connection to said shaft, through which pins 17 may be projected into engagement stationary arm 9, and operating to press said member 6 toward the sliding jaw 5. The friction member 6 is movable upon its its extension Ypivots and toward the jaw 5,

within selected ones of a series of openings 18 through the disks 15 in a circular series concentric with and around the shaft 111. To the ends of the arms 16 are pivotally secured the upper ends of connecting rods 19 extending upon both sides of the body 1, the forward and rear pairs of which are connected by cross bars20 to operating rods 21 extending from treadles 22 and 23. It will thus be seen that depression of treadle 23 causes downward movement of the forward end of the arm 16 and rotates shaft 1li in the corresponding direction te force the pivoted jaw 12 toward the jaw 5, by means of the disks 15 bearing with their peripheries thereagainst, and that depression of treadle 22 operates in a reverse manner to nieve jaw 12 away from jaw 5 and against the body 1, as shown in Fig. l.

From the foregoing it will be apparent that I provide a vise which may be readily adjusted to clamp, without necessitating the employment of the operaters hands with its adjustment, inasmuch as the operators body is designed to adjust the jaw 5 toward the jaw 12, and his feetto operate the treadle 22 in order to force the jaw 12 toward the jaw 5.

Having described my invention, I claim:

1. In a vise of the character described, the combination of a stationary body, a clamping jaw having an elongated hollow shank, mounted to slide through said stationary body, a spring actuated friction member mounted upon said body and extending within said movable jaw shank, to lock the same in. its adjusted position with relation to said body, a swinging jaw carried by said body, and treadle operated means to swing said last named jaw, toward said clamping jaw, substantially as described.

2. In a vise of the character described, the combination of a stationary body, a clamping jaw having an elongated hollow shank, mounted to slide through said stationary body, a spring actuated friction member mounted upon said body and extending within said movable jaw shank, to lock the same in its adjusted position with relation to said body, means for releasing said friction member, extending upwardly through said hollow shank, a swinging jaw carried by said body, and treadle operated means te swing said last named jaw toward said clamping jaw, substantially as described.

3. In a vise of the combination of a stationary body, a clamping jaw having an elongated hollow shank mounted to slide through said stationary body, a spring actuated friction member mounted upon the said body and extending within said movable jaw shank, to lock the same in its adjusted position with relation to said body, a swinging jaw carried by said body, spring means for normally holding the same against said jaw, and a treadle operated cam mounted upon said body and bearing against said movable jaw, to swing the same toward said adjustable clamping jaw, substantially as described.

4. In a vise of the character described, the combination of a stationary body, a clamping jaw having an elongated hollow shank mounted to slide through said stationary body, a spring actuated friction member mounted upon said body, and extending within said movable jaw shank, to lock the same in its adjusted position, with relation to said body, means for releasing said friction member, extending outwardly through said hollow shank, a swinging jaw carried by said body, spring means for normally holding the same against said jaw, and a treadle operated cam mounted upon said body, and bearing against said swinging aw, to swing the saine toward said adjustable clamping aw, substantially as described.

5. In a vise ef the character described, the combination of a stationary body, a clamping jaw freely movable toward said body, and having an elongated shank slidably mounted therethrough, a friction clutch cai'- ried by said body and engaging said shank t`o prevent reverse movement of said jaw, a jaw pivotally mounted upon said body in opposing' relation to said first named jaw, and movable toward and from the same, a treadle operated means to swing said last named jaw and force the same toward said lirst named aw, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
